'ro away, and dumped, of which the following is a specification.

My invention relates to improvenents in t'hehandling of and dumping of ores and other material which may be hoisted from 15 mines and other excavations and which is to be'carried away and dumped or unloaded, and `-is *especially adapted to those nines or other excavations where a bucket elevated by a cab'le or rope is used. p

The object of my invention or improvement is to provide a meansfor taking the bucket, filled with ore, dirt, or other material, "away from the mouth of the shaft or other *excavation and deposit the contents of said 2'5 bucket at a place desired, all of which is to be accomplished automatically with the excep't'i'on of the power that is eXerted by steam' *or *other agency in 'hoistin'g the bucket and 'its contents from the shaft or other excava- I attain these objects bythe mechanism illustrated in the 'accompanyiig drawings, in which the figures represent the several parts of the machine and refer to the same part in `each illustration.

Figure 1 represents a side elevatedview of the machinery the same as when erected and in operation at a mine or other excavation. 14 represents the cable; 13, the sheave; 16, the bucket; 16 the bail or handle of the bucket;

17, the short rope or cable attached to the bottom of thebucket and at the end of which is attached an iron or wooden ball 17. upright timber or beam supported by another bean 8, which, together with the sheave,form

what is known as a gallows-frameff 5 represents the beam, upon which an iron rail 6 is laid, said beam and rail being supported by standards 7 and 9. Fig. 1 shows but cne side, as both the gallows-frame and track or so rails are double-that is, two upright timbers 7, two supports 8, two rails 6, two beams 5, dac., which, standing side by side or running snairoL 64,030. No model.)

parallel, fconst-itute the mechanisn which supports the cable and carrier 15, which is handling the bucket and so tramming and dumping the ore or other material. 15 is the carrier, and 12 and 12 the device used in dumping the bucket. XVhere 14 15 16 16 and 17 and 17 are in heavy lines, it represents the position of the machinery when the bucket has been hoisted and before it has passed down the track or rails. The dotted lines show the position after the carrier has carried the bucket down the track or rails and dumped or unloaded the same.

Fig. 2 is a sectional end View of the track, showing the upright supports 9, which may be -made of wood or iron, the beam or railsupports 5, and the rails 6, and 10 the crossbeam, hereinafter mentioned.

Fig. 3 represents the dumping and unloading device 12 and 12% attached to the beams 5. 'This device consists of substantial iron -rods, fiat or round, extending below the track sufficiently to permit of a free passage of the bucket within the same as they extend downward, 12, and above that portion which eX- tends at right angles to 12, and is in shape as represented by 12% A Fig. 4 represents a side View of the carrier 15. 18 is the carrier-wheels; 18% the point of axis, pivot, or shaft for each of saidrwheels;

l one side of the carrier, or'what may be termed side plate. 20 is the lever which operates the clutch 20, hereinafter mentioned. The carrier-wheels are ordinary fianged iron wheels, such as areused on ore-cars, railroadrails until forced forward, as hereinafter de-v scribed. In this figure (Fig. 4) the catch or starterhas been omitted and is shown by Figs. 9 and 10.

Fig. 5 is the same View of carrier and track as Fig. 4, but with the weight of thebucket or :bucket and contents resting on the carrier. The weight has changed the center of ICO gravity of the carrier, elevated the wheels farthest fron lever 20, and depressed or lowered wheels uearest said lever. In this figure the catch or starter has been omitted.

Fig. 6 is an inte'rior view of the carrier along line Y Y shown in Fig. 8. In this figure, 18 represents carrier-wheels. 19 represents sheave in carrier for cable; 20, clutch; 20% open groove iu clutch, in which is pin 21 to regulate the distance the clutch may move in either direction. 20 is clutch-lever; 6,rail; 5, track-bean or bed; 18% pivots, &0. 14" shows position of iron ball on cable or rope as it rests ou sheave and clutch. In this position the carrier supports the bucket orbucket and its contents and is as it is in passing down the incline rails or track. In this figure the catch orstarterhas also been omitted. Fig. 7 is the same machine, showing the cross-beam 10, whichis at the end of the rails or track or placed at the point where the bucket is to be dunped and the beam against which the lever 20 strikes and in so striking throws the clutch 20 from the position shown in Fig. G to the position shown in Fig. 7. In this figure the catch orstarter has also been onitted.

Fig. 8 is looking down on the top of the carrier, but does not show the catch or Starter. Fig. 9 shows substantially the same as Fig. 6,with the addition of the catch or starter 23. Fig. 10 shows the catch or starter, which is an iron rod bent to the shape represented by 23 and 23 in Fig. 10, which is attached to the pivot 22, which is adjusted in the side plates 15 of the carrier, so that the same will rise and fall when acted upon by the iron ball 142. It will be observed that the cable or rope passes through the starter at or near the point 23 and that the Starter 23 is only acted upon when the ball lat is elevated. In Fig. 9 the heavy lines show the starter at rest. (See heavy lines 23.) The dotted lines 23 show the starter elevated bythe iron ball 14,which in so acting lifts the back portion of the carrier, and the tension or strain on the cable of the cable so acting on the Starter gives the carrier a forward notion, starting it down the icline track or rails. It will also be observed that the same impetus is given to the carrier when the bucket is loaded and the weight thereof falls upon the clutch, changing the center of gravity to a point in front of the middle wheels, as shown in Fig. 5.

The mechanism used in this invention consists of what`is known as an ordinary gallows-frame equipped with a cable or rope, to which is attached a bucket, and which,in connection with some power, such as steam or other, is used in hoisting or raising ore, dirt, or other material, and to which has been added an incline track or inclined rails, at the top of which inclineis the bend ornotch, (6,`

Figs. 4 and 5,) equipped with a carrier and du mping device, as shown in the illustrations, together with an iron ball, which is bolted to the cable or rope above the bucket, and also with a short cable or rope attached to the bottom of the bucket and on the end of which is attached an iron or wooden ball. The carrier itself consists of two heavy iron plates or sides properly adjusted together by means of the pivots or axles of the six fiange-wheels which support the carrier in its movements up and down the track or rails. Between the two plates or sides of the carrier is the T- shaped clutch 20, acting upon the pivot or axle 18% and the pin 21, which is firmly fixed in the side plate 15" and operates in the groove 20 Also between said plates orsides of the carrier is the sheave 19, Whicl revolves upon its pivot or axle and upon which the cable or rope acts when the bucket is being dumped, &0.

To understand the operation of the above mechanism and to see the results attaincd, let us note the following illustration: We are at a shaft over which has been erected the gallows-frame and incline track and the same equipped with a cable, carrier, dumping de- Vice, sheave, bucket, and iron balls above nentioned and depicted in Fig. 1. The power to lower and raise the bucket is at the other end of the cable or rope and operated by an engineer. The cable itself passes from the power up and over sheave 13,then passesdown through the carrier, between the two sides or plates thereot, and between the sheave 1!) and the clutch 20, which brings it also between the two rails of the track on down to where it is attached to the bail of the bucket l6. Before using the inachinery the engineerwill see that the iron ball 14 is below the track. The position of the carrier will then be as in Fg. 4, its weight resting upon the four rear fiangewheels, with the two rear wheels rcsting in the bend or notch G in the rails 6. clutch 20 will then by force of its own weight rest against the rope or cable, as in Fig. 6. (Note, however, that the iron ball 14 will be below and not as seen in Fig. 6.) It will now be observed that the bucket can be lowered or raised without affecting the carrier until such time as the engneer shall raise the bucket so far as to bring the ball 14: up through the carrier and beyond the clutch 20. Suppose the bucket at the bottom of the shat't and loaded. The engineer starts the power and the bucket is raised. In passing up the ball 14 passes through the carrier, slightly raises the clutch 20, and passes out above the carrier. As soon as it has passed through the carrier clutch 20 falls back against the cable or rope to the position shown in Fig. 6. The eugineer reverses the power and the ball desceuds and presses on the top of clutch 20 and against the sheave 19 at a point on said sheave slightly above a line drawn horizontally through its center, so that it is then in the position represented in Fig. G, wit'h the entire weight of the bucket and its contents resting on the top of clutch 20 and the sheave 19. When the weight so falls upon the clutch and sheave, it brings the center of ICO The

IIO

gravity of the carrier to the front of the two i middle flange-wheels and nearer to the leve'r By so doing it presses down the two front wheels or those near lever 20and raisesthe' rear wheels out of the notch 6 and the engineer byallowing the cable'or rope to run out (owing 'to the space between the tracks or rails being free of all cross-beams or obstructions) permits the carrier, with its burden, to pass down the incline rail 6. The carrier in so passing down the incline carries the bucket along under the track and between the two erates the ball let' and allows the bucket to descend, and in its descent it is turned upside down by reason of the ball 17 being held in the dumper 12 as shown by the dotted lines in Fig. 1. Incase the bucket had been raised from the shaft empty and there had not been sufficient weight lowered onto the front part of the carrier to start it down the iucline the 'engineer would simply raise the' bucket so high that the ball 14: would catch in the starter 23, Fig. '9, and by raisin'g still higher the starter would raise the rear end of the carrier and so start it forward on the track. The bucket having been unloaded, it would lang, as per the dotted lines in Eig. 1, with the ball 14 as there shown, and theposition of the clutch 20 would be' as shown in Fig. 7, or closed to receive the ball at the lower part thereof. The engineer then exerts the power the same as if raising the bucket from the shaft, the bucket ascending toward the carrier, the ball 14 comes in contact with the clutch 20 and sheave 19, as shown in Fig. 7, and not being able to pass through the carrier and the power still being applied drags the carrier back up the incline or track and throws it into its originalposition, as in Fig.

g 1, and, being relieved of its burden, the carrier drops into the notch .or bendin the track or rails 6 on its rear wheels, as in,Fig. 4. The

engineer thenreverses the power, lowers the bucket, and the 'ball descends from its position, as in Fig. 7. Olutch20, then released; falls of its own weight and is in position to permit the ball again to pass up through,

when the bucket ascends with a new load.

The carrier is made of 'sufficient weight to overcome all tendency to start back up the incline from cable tension before compelled to do so by reason of the ball and clutch posi'- tion shown in Fig. 7. In case 'the incline track is extende'd so far that there .wouldbe. a tendency on the part of the railstospread the uprights 9 are eXtended above the track far enough to permit of cross ties or .beams being bolted across the tops, leaving room for the carrier to pass between the u prights and below the cross-beams.

lam aware that vertical hoists or gallows frames are used and that buckets are'dumped by man-power and by other devices, such as ,a rope and hook attached, to a ring in the bottom' of the bucket, and that tracks are tlaid upon the ground and at elevations and ore and other material trammed and dumped by man-power and in other ways; al so, that a machine has been patented for self-dumping, in' which the she'ave 13 in Fig. 1 is in a car or frame on wheels and drawn toward the engine or power; but it does not carry to the dump nor away from the power and is in the nature of amovable sheave-wheel, such as 13 in Fig. 1, only that in Fig. 1 it is permanent, nor has any machine. a carrier in any way similar to the one in this invention, so with all' of those ,I have nothing to do; but

WhatI do claim, as my invention, and desire to secure by Letters Patent, :is-

1. In a hoisting, conveying and dumping apparatus, an inclined raised track having a depressed portion, incombination with a carrier having wheels at one end adapted to rest in said depressed. portion andraise wheels on the opposite end of said carrier from said track, a receptacle depending froma rope,

and means connected with said rope and car` rier forsuspending said receptacle from said carrier so asQto tilt and startthe latter, substantially' as' described. y
